I would like to see end results after couple of shaves. i am sure pastes give sharpest edge but problem is with smoothness and keeping the edge. Jim Please shave couple of times and see how edge acts. I don't know too much about pastes except chro2.
I remember in one razor i had problem to make final edge it was just braking down i ended up using diamond past.It happen in the meeting which didn't have too much time to work on the blade.

1 more i think it will better if you use balsa.it is cheap and you wont loose your past after using ones.
Thank you
